Battery charger QOLTEC 12V 5A rectifier for AGM/GEL batteries

Description: Excellent efficiency thanks to intelligent controlMicroprocessor-controlled charger, guarantees total safety of use, it is personalized charging for each type of battery, automatically when the battery is fully charged, it shuts off keeping the battery ready. So you don't have to worry about overcharging the battery. You can charge your battery safely and quickly now. The product has advanced safety features including reverse polarity, overvoltage and overcharging protection. Excellent performance through intelligent controlChoosing the right charger for your battery is extremely important if you want your battery to serve you for a long time. An inappropriate charger can not only result in longer charging times, but also significantly shorten the battery's service life. A Qoltec charger offers microprocessor-controlled precision charging, so you only need one charger for different types of batteries. The time required for charging depends on the degree of discharge of the battery and its actual capacity. The charger is designed for charging 4-80AH batteries in cars, motorcycles, boats, lawnmowers and quads.Precise charge management in three stepsThe charger provides a 6-stage charging process. Each stage is controlled by an electronic circuit, allowing the device to adjust the voltage and current to the current state of the battery.Diagnosis the charger analyses the battery condition,Bulk Charge intensive charging with a constant current of 5A until the nominal voltage is reached,Absorption Charge the voltage is maintained at a constant level and the current gradually decreases to prevent overcharging,Float Charge the charger maintains a float voltage, preventing the battery from self-discharging,Power maintenance ensures that the battery is ready for immediate use,Stand-by / Recond after full charging, the battery is periodically monitored and recharged if necessary.Simple installation - robust housingConnecting the charger to the battery is quick and easy, simply attach the clamps to the battery accordingly. The red connector is clipped to the positive terminal and the black one to the negative terminal. Any vehicle owner should be able to cope with this. Once the charger is connected to the power supply and the appropriate mode selected, the charger is ready for charging. | Filters / protection: Surge | Filters / protection: Current too high | Filters / protection: Circuit | Filters / protection: Voltage drop | Batteries included: No | Accessories included: 1 x Charger 1 x Warranty card 1 x Operating instructions | Color: Black

How to use

Connect the charger to the battery following standard polarity: positive to positive and negative to negative. Ensure the power supply is disconnected before connecting to prevent sparks. Once connected, apply mains power and allow the charger to run through its charging cycle until the float stage is reached; the device supplies a controlled 5A current during bulk charging and reduces to a maintenance level when the battery is fully charged. For routine maintenance, the charger can remain connected for extended periods in float mode to keep the battery topped up.

Recommendations

Use the charger in a dry, ventilated location and avoid covering the unit during operation. Verify compatibility with the battery manufacturer’s recommended charging voltage for AGM and GEL types. Periodically inspect wiring and connections for corrosion or damage and disconnect mains power before performing any maintenance on the charger or battery.
